SELF--GENERATING HYDROCARBON-GAS STOVE.

SPECIFICATION forming part of Letters Patent No. 247,239, dated September 20, 1881.

Application filed May 9, 1881. (No model.)

To all whom it may concern Beit known that I, ADELBERT M. BRAINARD, of Chicago, State of Illinois, have invented certain new and useful Improvements in Self- Generating Hydrocarbon-Gas Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates, principally, to the auxiliary burner, or the burner for initially heating the generator, of a self-generating hydrocarbon-gas stove. Its object is to avoid the ignition of the liquid hydrocarbon itself in heating the generating part or parts in startin g such stove.

To this end the invention consists in the several novel devices and combinations hereinafter fully explained and pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a hydrocarbon-gas stove containing my improvements. Fig. 2 is an end elevation of the same. Fig. 3 is a central vertical section of the parts immediately related to the generator and burner in a central, longitudinal, vertical plane of the stove. Fig. 4 is a vertical, transverse section of the said parts through 4 4, of Fig. 3. Fig. 5 is a detail in plan.

Ais the top of the stove, having sunk portions B about the burner L, and supported by the legs C.

D is a shelf, secured to the legs C, and supporting a reservoir, E, for holding liquid hydrocarbon.

F is an air-box, connected with the reservoir E by the pipe F, which leads to near the bottom of the reservoir, and is provided with a stop-cock, F

G is a pump or equivalent device for forcing and compressing air into the shell F. Said pump is operated, as here shown, by the crank H, suitably attached to the stove top or frame, and connected with the pump-piston rod g by the pitman h.

I is a main pipe, extending from near the bottom of the reservoir E upward and along,

beneath the burners, and J J are branches leading from said main to the several generators, N, as more clearly seen in Figs. 3 and 4.

q J is a press-cock, arranged in the usual manner to cut off or regulate the flow of liquid to the generator.

K is a small tube leading from the top of the reservoir E upward and along in proximity to the branch pipes J, and opposite each of said pipes it is provided with a fitting or burner, K shown in Figs. 4 and 5. Said fitting or burner has an aperture, 70, which is directed toward the tube J, or toward the generator N, and is stopped by a press-cock, K.

K is a pipe leading from the generator N to theinterior of the burner K or of the pipe K.

L is a pipe leading from the generator to the burner L.

In the operation of the machine constituted as described air is compressed into the shell F and into the space above the liquid hydrocarbon contained in the reservoir E, and when the valve J is opened is forced into the generator N, such pressure of the air serving in place of the head sometimes given theliquid for the purpose of conveying it to the burners. The air, long confined over and in contact with or forced through the hydrocarbon liquid in the reservoir E, is carbureted and is inflammable. Said carbureted air being conducted in the pipe K to the burner K when it is desired to start the generating apparatus the cock K is opened, and the inflammable air is ignited at the mouth of the said burner K The flame impinges on the pipe J or generator N, or both, and soon heats them hot enough to vaporize theliquid containcdtherein or admitted thereto. The shield M, surrounding the burner-mouth and the tube J below the generator, confines the fiamein contact with the parts to be heated, and hastens the operation.

By means of the large storin g-room aflorded by the air-box F, ample volume of carbureted air may be supplied to the burner to heat the generator without reducing the pressure upon the liquid in the reservoir E below a degree necessary to raise said liquid to the generator; but as it may be desired to maintain a constant flame at the burner K so that when the main burner is not in use it may be extinguished and then instantlylighted again when required, the pipe K is provided, connecting the generator N with the burner K whereby (the cock J being open) this burner may be supplied with gas from said generator, instead of air from the reservoir E. In this case the burnerpipe L should be provided with a cock, L and the pipe K should also, preferably, be provided with a cock, k.

The apparatus here illustrated is made more compact by using the single chamber of the reservoir E to contain the liquid for carbureting the air and to supply the generator, but separate tanks may be used.

Any device to more perfectly effect the carbureting of the air may be employed in the carbureting-chamber, if desired.

By making the supply-tube E to discharge into the reservoir E at a considerable distance below the top of the latter, as shown, a space will always be available above the liquid in said reservoir to contain carbureted air, and to allow its free passage into the pipe K.

I claim as my invention In a self-generating hydrocarbon-gas stove, the combination of the generator N, the reservoir E, having its inlet belowithetopymeans for compressing air above the liquid in said reservoir, the burner K and the connecting pipes I, J, and K, arranged and operating substantially as described, and for the purposes specified.

In testimony that I claim the foregoing as of two witnesses.
